RAIL ANCHOR.

Application filed August 16, 1926.

This invention relates to new and useful improvements in rail anchors and particularly to anchors of the two piece type, and the main object of the invention is to pro vice a rail anchor having means whereby the same may be easily and quickly secured to a rail to hold same against creeping tlirough any of the well known causes such as changes in temperature, or tl'irough forces exerted by a train passing thereover.

Another object is to provide a simple and easily manufactured rail anchor which will be economical and ellicient in service.

In my invention T provide a rail anchor built in two sections. One section namely the main body portiom contacts with the bottom and one side of the rail flange and exti. .de in the transverse direction of same, while the other SGLLlCIl which is wedge shaped adapted to with the other side of the rail flan and with the main body portion and also with the tie. On the sides of the wedge shaped section and the main body portion, in proximity to the rail ila'nge edges, reesses are formed and into said recesses are placed inserts having curved serrated edg s which contact with the rail and bite into same to lock the device in rail anchoring position.

In the drawings which illustrate my invention, in one of its forms;

F igure 1 is a plan view oi my improved anchor in position.

l igure 2 is a side elevation of the anchor. iigurc 3 is an end elevation oi the an chor.

Figure at is a plan View of the wedge shaped strut or tie contacting member.

l igure 5 a front elevation of the device shown in Figure l.

Referring more particularly to the drawing-rs l1 designates the main body portion ot the anchor which extends from edge to edge of the base of the rail 12, and across the bottom 13 thereof. The main body portion is preferably made of channel cross section suitably ribbed to strengthen same. Projecting upwardly from and formed integral with one end or the portion 11 is the guide 1- the edge 15 of which is substantially parallel to the edge of the flange of the rail and projects inwardly toward same, forming a channel shaped guide for the wedge shaped strut or tie contacting section 16. The vertically disposed side 17 of the Serial No. 129,593.

guide 14 is curvedin the form of an arc in the longitudinal direction of the rail so that the tapered side 18 of the wedge shaped strut will make linecontact with the verti cally disposed guiding surface 17. Projecting upwardly from the body portion and in the end remote from the guide is the holder 19, the edge 20 of which, adjacent the rail flange edge 21, is curved in the form of an,

arc to facilitate placing the anchor in position. A dovetailed recess 22 is formed in the projection or holder 19 and into. this recess is placed or cast the insert 23", the edge Q l of which is curved to the same radius as the edge 20. The edge 24 of the insert is serrated or, provided with teeth 25' which contact with the edge of the flange of therail. The edge 26 or" the strut or wedge shaped section of the rail anchor adjacent the rail bottom edge is provided with a groove 27., which allows the edge 27 of the rail flange to fit thereinto, The wedge shaped strut 16 has also. a vertically disposed surface 28 which contacts with the vertical face of the tie 29 when the device is in the rail anchoring position. The grooved portion 27 of the strut 16 has a recess 30 preferably, but not necessarily, of dovetailed form, into which is placed an insert 31 similar in shape to that placed in the main body portion projection or holder 19. This insert is provided with serrations or teeth which engage with the edge 27 of the flange of the rail. The wedge shaped section or strut has also a small area within the groove 27 which contacts with the edge of the rail, and positions the strut when assembling the anchor,

Tn attaching the device to a rail, the strut or wedge shaped ra'l contacting member is placed with the surfaces 28 in contact with the tie and the groove 27 covering the edge 2? ot the rail. The main body portion is then placed with its length in the transverse direction of the rail and the guide surrounding the wed e shaped section. By holding the main body portion manually and applying light blows with a hammer on the side remote from the tie and from the wedge shaped strut, the serrations of the inserts are brought in contact with the edges o1 the rail flanges and bite into same to hold or lock the sections in contact with the rail and in such a manner that the wedge shaped section of the anchor acts as a strut to trans-- mit any forces set up by railcreepage from the rail to the tie. p

The device is very simple in construction and can be economically manufactured. It will be seen that the device may be very easily secured in position and that once it has been applied to a rail it will loci; the rail and prevent creeping of same. It requires practically no inspection or examination once ithas been installed as any tendency which movesthe main body portion of the anchor away from the tie onl tends to lock the device more securely to the rail.

Having thus described my invention, what I claim is;-

1; A rail anchor comprising, a main body portion adapted to extend transversly ot a rail and having an upwardly turned portion at each end, one grooved to form a guide, and a wedge shaped member. fitting into said guide and groovedon one side to fit over the edge of the rail flange, and metal inserts fitting in receses in the main body portion and the wedge shaped portion on their sides adjacent the rail flanges, said inserts having toothed projections adapted to out into the edges of the rail flanges.

2. A rail anchor comprising a main body portion having a grooved guide formed at one end and an upwardly turned holder at the other end and a wedge shaped tie contacting member fitted into said grooved guide, said wedge member having a groove formed in the side thereof adjacent the rail flange to allow the edge of the rail flange to pass thereinto, and hard metal inserts fitting in recesses formed in the holder and the wedged member on the sides in proximity to the rail, said inserts having teeth on the rail contacting faces of the inserts said faces being made in the form of an arc to facilitate the attaching ot' the anchor to the rail.

3. A rail anchor made in two portions, one portion being adapted to extend across the rail and provided with a grooved guide on one end and an upwardly turned holder at the other end, the vertical face of the guide being made in the form of an arc, the other portion of the anchor being wedge shaped and adapted to fit into said guide and provided with a rail tie contacting face, and a grooved surface adapted to fit over the edge of the rail flange, and metal inserts fitting into dovetailed recesses formed in the faces oi the holder, and the wedge shaped member adjacent the rail flange, said inserts being provided with toothed projections on the surfaces in proximity to the rail, said surfaces being curved in the form of an arc to facilitate attachment of the anchor to the rail.

In witness whereof, I have hereunto set in hand.
